A multifunction oven with a steam-cooking function can complement or replace several kitchen appliances: a steam oven, fan oven, grill, air-fryer oven or – depending on the model – even a microwave and rotisserie. However, the wide range of functions makes comparisons more difficult. Many appliances advertise numerous programmes, even though important details such as cooking-chamber capacity, water supply and cleaning requirements are often more decisive in everyday use.
This buying guide from the Joybuy Product Recommendation Officer explains what households, families, keen home cooks and space-conscious consumers should look out for.
An appliance described as “10-in-1” may offer numerous operating modes, but it still needs enough space for the dishes you want to prepare. A small mini oven may be sufficient for bread rolls and individual portions, while families are more likely to benefit from a cooking chamber of around 20 litres or more.
It is not just the external dimensions that matter, but also:
A steam oven needs a reliable water solution. Some appliances require a container to be filled manually, while others have a removable tank. The key considerations are whether the tank is large enough, easy to access and simple to clean after use.
Steam helps control moisture during cooking. However, this does not automatically mean that every dish will be lower in calories or nutritionally superior. The cooking method, ingredients and portion size remain the deciding factors.
Steam, grease and crumbs collect on the interior walls, base and accessories. Programmes such as AutoClean or steam-assisted cleaning can soften residue, but they do not replace wiping the appliance afterwards. Removable parts and a smooth interior surface wherever possible can reduce the effort required for cleaning.
Before buying, measure the available worktop space carefully. A countertop oven or multifunction microwave also needs clearance from walls and wall units. The manufacturer’s specific requirements are decisive; for example, the Bauknecht MF 259 SG recommends sufficient clearance above, behind and at the sides.
A capacity of 20 to 25 litres is often suitable for smaller households and everyday portions. A 24-litre combination oven may also be designed for several snacks, baked goods or a whole chicken. Its actual suitability depends on the interior dimensions and accessories supplied.
Not every function will be used equally often. So consider whether you really want to use the following operating modes:
A microwave with grill and fan cooking is practical if reheating is a priority. If you mainly want to bake and steam-cook, you should pay greater attention to the interior space, temperature control and water handling.
Wattage indicates the electrical power of individual functions, not necessarily the quality of the cooking results. Several power levels are useful for microwaves, while an adjustable temperature and adequate ventilation are important when using the grill.
You should also look for:
Steam programmes pose a risk of scalding from escaping hot steam. The door should only be opened after an appropriate cooling or venting period.
Why this product suits the profile: For smaller households that mainly want to reheat, defrost and occasionally grill, this compact appliance offers straightforward controls with rotary dials.
The range of functions is clearly defined: 20 litres, 700 watts of microwave power, 900 watts of grill power and nine settings instead of a confusing list of programmes.
Glass turntable with a diameter of 24.5 cm, combinable microwave and grill functions, plus automatic switch-off and overheat protection according to the product description.
Why this product suits the profile: The combination of microwave, fan cooking, quartz grill and steam-cooking function suits households that want to bring several cooking methods together in a limited amount of worktop space.
The flat 25-litre cooking chamber without a conventional turntable makes it easier to position larger, rectangular containers and clean the base.
800 watts of microwave power, 1500 watts of fan-cooking power, 1300 watts of quartz-grill power, steam programme, Crisp function and AutoClean according to the product data.
Why this product suits the profile: Keen home cooks and families get a countertop oven with steam, fan cooking, air-fryer, baking, keep-warm, dehydrating, proving and rotisserie functions.
The removable 1-litre water tank makes the water supply easy to understand. The interior is specified as 304 stainless steel; the accessories and interior should nevertheless be cleaned regularly.
24-litre cooking chamber, automatic 360-degree rotisserie and seven accessories according to the supplier; designed for poultry weighing up to 2 kg.
Why this product suits the profile: For gardens, camping, picnics and tailgating, a standalone charcoal grill is more suitable than an electric multifunction oven designed for the worktop.
Its intended use is clear: this appliance is designed exclusively for outdoor use and should not be used as an indoor oven.
70 × 35 cm grilling area, folding legs, two side shelves and rotisserie with hand crank; the net weight is 9.6 kg according to the product details.

Running costs depend on power, usage time and operating mode. A microwave often heats small portions more quickly than a large oven. Fan cooking and grilling, on the other hand, require a preheating phase. Steam programmes also use water, with consumption depending on the programme and its duration.
Simple routines can help extend the appliance’s service life:
In addition to the stated external dimensions, you must allow for the ventilation clearance specified by the manufacturer. Also measure the depth of the worktop and check whether the door can be opened fully. A 20- to 25-litre appliance takes up less space than a large built-in oven, but it is not automatically suitable for every baking tin.
Steam can soften dried-on residue, but it does not remove grease and food remains completely by itself. A removable water tank, smooth interior surfaces and dishwasher-safe accessories can make cleaning easier. After steam cooking, the interior should be ventilated and wiped dry.
Service life depends on build quality, frequency of use, care and correct operation. A general figure in years would not be reliable. Look for available spare parts, warranty terms, clear operating instructions and a safe location with adequate ventilation.
